Beschreibung

This technical rule G 469 can be applied to the pressure tests of pipelines and installations which are not used for the pipeline-bound supply of gas to the general populace, if the specific properties of gases and other existing regulations, if applicable, are taken into account.

For pipelines and installations that fall within the scope of the High-Pressure Gas Pipeline Ordinance (Verordnung über Gashochdruckleitungen; GasHDrLtgV, the design pressure (DP) is relevant for the specification of the test pressure. For all other pipelines and installations, the test pressure is based on the maximum operating pressure (MOP). Consequently, the following chapters will mention both the design pressure and the maximum allowable operating pressure in the sections concerning the test pressure requirements.
